im not going to say anything different from any of these guys so im not going to post the questions. heres my .02. this guy is a dumb ass! cams are a really important part of a NA motor, they can give you as much as 25whp with the right tune. a stock ls/vtec would beat a b16 with bolt ons. i have a ls/vtec with some small bolt ons, i will give him a run for his money. i hate people like this that think they know eveything, im far from know everything but i know alot. well i guess thats all i have to say. just tell this guy to go home next time you see him.
